v In the accompanying drawings the preferred form of the invention has been shown.

other mechanics, one of the objectsofthe and cl'aimedyit being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing In said drawings v Figure 1 is a central longitudinal section through the burner. Fig. 2 isa section on line 2-2, Fig.v 1. Referring to the figures by characters of reference 1 designates a frusto-conical burner head, the' front or small end of which is open while the rear end or base has a central aperture 2. The wall of this head is provided with openings 3 through whichfair will `be admitted to be ,mixed with thecombustible vapor `discharged from the nozzle' of the burner as hereinafter explained.

The head 1 is formed with a longitudinal enlargement 4; which projects into thehead and also beyond 'the outer surface thereof.

Y This enlargement also extends rearwardly from the head( Formed on the rear portion of the enlargement is an angular vextension 5 having a forwardly extending nozzle 6 and a rearwardly extending tubular arm 7.

The arm isinteriorly screw threaded as at i 8 to receive a threaded valve stemt). A nee-.-

dle valve 10'extends from the stem 9 andis adapted to project into and close a tapered i' vent 11 formed in nozzle 6. A screw cap 12 engages the arm 7 Vand serves to press packing 13 around the stem 9. This stem can be rotated by means able construction.V

An extension 15 projects downwardly from the rear portion of the enlargement 4 andis by i' removing the screw fof a handle'lf of any suit? Y ends thereof.' t

exteriorly :scr/ew threaded-as at eni gagementbythe' wall "of'an aperture 17 lformed-"inafpriming cup 18'. 'Extension v15 has a threaded bore 19 inwhichis screwed one vend of -a feed `pipe 20,1

Parallellongitudinalbores and 22 are formed in thefen'largement Il,v these bores bet ing extended from the `back end of said enlargement to 4points'close to the front end thereof. The bores are here connectedby a radial`bore'23 extending into the enlarge- `mentfrom the "bottom"thereof,V The 'bores '21, 22 and 23. areclosed at their outer ends by screw plugs 24. Bore 21eommunicates Y With recess-'l5 througha port 25 and afbore 26 is extended'downwardlythrough the extension 5V and communicates. with the stem receiving passagein the said extension.` The vo'ut'er`end-of the bore 26 is adaptedk to be closed by a-screwv plug 27.1` A protecting hood'28 is fit-ted varound the rear or base portion of th'ehead 1 andfits snugly against the'extens1on7 so as to enclose the burner 6. y

VThishead can be slipped lback against the 'cap 12A to give access to the burner 6.

In using thedevicev priming fuelrl is placed in the cup 18 andlighted.` VFuel admitted to the bores21 and 22 from the pipe 2O will thus be vaporized and will 'escape through the bore 26 and thek nozzle 6. The e iso.Av

outflowV of this fuel can be controlled by needle valvef10. p The jet of fuel will be directed ffromthe nozzle into the head '1 where it will mix with air admitted through the opening 3 so asto produce a highly ,combustible mixture. This mixture can' `be ignited atV the outlet end of the head. i e e Obviously theheat generated will result invvaporizing the-fuel in the bores 21 and 22 so that further use' ofthe cup 18 vis unnecessary. It will be noted that the plugs .24

are so positioned thatY when they are removedl any fuel trapped in the inclined bores 21 and 22 will be free toyflow into the cup 18 Vandused'for priming purposes. e

Importance is attached to thefactthat the different bores are vdisposed at` such 1 yangles as toi-be readily formed in the de-V vice for .the purpose ofproducingthe pas- 'sa-ges at the desired points.4 Likewise all of these bores can bel cleanedA easily simplyl What is claimed is plugs at the outer" lio prising a Vcombustion head which is open at one end and has an integrally formed closure at thevopposite end with an inlet `aperture therethrough, an elongated generator body formed'integrallywith'= saidv v head and projecting for some distancebeyon'drthe rear end of the head, said vbody being of relatively'uniform cross section and having avsubstantial portion thereof projecting into the` combustion chamber, said generator body having an extension at its rear Y end for connection with a. supply pipe and -the outer end of said connecting bore, an inllet port in the irst named extension leading rtothe lower, one ofthe: parallel bores, an

outlet port leading from the upper parallel bore through the T-shaped projection, a

vscrew plug for closing the upper end of vsaid last named bore, said Tv-shaped projection also l'having a longitudinal passageway with an outlet orifice adjacent to said inlet opening, and a valve for controlling the outlet orifice. a i n e 2. blow torch comprising a east metal combustion chamber having a wall Vat one "end with an inlet aperture therethrough, an` elongated generator body cast vintegrally projecting `Vinto the combustion chamber,

means atv the rear end ofthe generator ybody for securing 1t to a supply member, anupwardly extending integrally formed projection at the rear end of the generator body, said torch having a tortuous passageway leading fromthe connecting means through the lowerportion of the generator body to the i'ront end thereof, then upwardly and back through the generator body, and then 'up- Wardly through said projection to an outlet adjacent to said inlet aperture in the head, the portions of said passageway through the generator body being-straight and substantiallyparallel, a valve for controlling 'said outlet, n and a hood covering the valve and adjacent portion of they head, substantially 'as described Y 4 In testimony that I claim the foregoing as my own, I have hereto aflixed my signature.
